FLYTRAP.

Application lecl June 19, 1922.

To @ZZ whom t may concern:

Be it known that I, JAMES l/V. HiLnRn'rH, la citizen of the United States, residing at or' Ohio, have invented new and useful lmprovements in Flytraps, of which the tollowing is a specification. n

The invention relates to improvements in fly traps.

The object of the present invention is to provide a simple, practical and efficient iy trap of strong, durable and inexpensive construction designed 'for use on door, window and other screens and capable ot being readily applied to the same without necessitating any alterations in the construction thereof and adapted to cause the flies crawling up the screen to trap themselves.

A further object of the invention is to provide a iiy trap of this character adapted to be easily and quickly removed from a screen frame for destroying the trapped flies or tor any other purpose.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts `hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacricing any oi the advantages ot the invention.

In the drawings, in which like characters of reference designate corresponding parts in the several views Figure l is an elevation of a fly trap constructed in accordance with this invention and is shown applied to a fly screen.

Figure 2 is a vertical sectional view ot' the same, the section being taken through one ot the hollow conical trap members.

Figure 8 is a rear elevation of the ily trap detached,

Figurel is a horizontal sectional view through one side of the tly trap and :[iy screen.

Figure 5 is a detail sectional view illustrating the construction of the locking devices for securing the fly trap to the fly screen. j

Figure 6 is a detail view ot one of the hollow conical trap members.

Serial No, 569,188.

ln the accompanying drawing, in which is illustrated the preferred embodiment ot the invention, l designates a. rectangular screen v.trame provided at the inner edges of the trame bars or members with interior projecting beads 2 overlapping and securing the marginal edges ot the screen material or wire netting 3 to the screen frame, The iiy screen frame may consist ot a door, or window or other fly screen and the iiy trap is mounted upon the upper `portion thereof and interlocked with the top and side beads 2 of the ily screen. The Hy trap comprises a rear support 4.- having a groove 5 adapted to receive and fit the top bead ior holding the trap against vertical movement on the {iy screen. The said rear support is composed of a bar 6 and a transverse series of tapered blocks 7 attached to the lower edge of the bar G, which is recessed at the lower edge contiguous to the blocks to lorm there. with the said bead receiving groove The blocks project rearwardly at the said recesses to form the lower wall of the groove V1 and the end blocks are provided vith straight vertical outer side edges 7 which Vlit between the vertical side beads 2 ot the screen `trame. By this construction the rear support is interloclred with the screen iframe and held against vertical and lateral movement thereof and it is detachably secured to the screen frame by means ot substantially l.shuped locking devices 8 mounted on the screen frame at the sides thereof and consisting` et' stems and projecting arms. The stems term pivots to permit the arms to be turned into and out of engagement with the terminal projecting portions 9 oit the bar 6 and when the arms ot the locking devices 8 are turned down out oi engagement with the said terminal portions 9 et the bar G the trap is adapted to be removed irom the screen 'frame and may be replaced thereon.

The inner opposed side edges l() of the tapered blocks converge upwardly and 'form flaring entrances to the tly trap and the blocks have secured to them inner and outer transverse strips 1l and l2 of screen material. rilhese transverse strips ll and 12 of screen material bridge the spaces between the blocks and coniine the flies crawling up the screen between the converging edges l() and cause the flies to pass upwardly through the contracted portions of the tapering spaces between the blocks and enter hollow conical. trap members i3 constructed of screen material and mounted uponthe rear support t and located within and projecting from the support at an upward inclination. The hollowv conical trap members are provided at the bottom and sides with marginal attaching portions la which are secured to the rear support and the said trap members are provided at their upper ends or aperies with openings i6 to permit the flies t0 pass from the trap members into the receptacle 1G. The receptacle lli consists of segmental end Walls i7 and 18 and. a connecting Wall 19 ot' screen material. rllhe connecting; Wall of screen material is of substantially semicylindrical form and is suitably secured to the grooved edges ot the Walls and is preferably formed integral with the front strip l2 ou" screen material. .lheend Wall 18 is provided with an opening' 20, which is normally covered by a pivoted closure plate 21 constructed of sheet metal or other suitable material and secured to the end Wall 18 at the upper portion thereof by a pivot 92 and provided at the lower portion with a projecting lug Q3 forming a` grip or handle by means ot' which the pivoted `closure may be readily sivung open and returned to its closed position coveringthe opening 2O of.

the end Wall 18.

The flies 'crawling up the screen will pass into the darin entrances to the fly trap and be directed by the upwardly converging' Walls thereof to the conical trap members from which the flies u'ill emerge into the trap receptacle i6A The fly trap, when a sufficient number ot flies have been captured, may be readily removed to enable the flies to be destroyed by scalding or other means and the dead flies may be readily emptied through the opening 20. Bv this means the trap may be maintained in a sanitary vcondition. The trap presents ay neat and artistic appearance and will not be objectionable -when applied to either a screen door or a window screen.

lfilhat is claimed is:

l. A 'fly trap including` a rear support adapted to fit against a fly screen and provided with a groove arranged to receive the top bead of the screen trame7 said rear support being also provided with a transverse series ot tapered blocks fitting between the side beads of the fly screen and formino' intervening tapered entrances. the said proove and the block interlocking` the rear support `with the fly screen against vertical and lateral movenu-mtD fasteningr means for detachably securing the rear support to the screen frame, a receptacle mounted on the rearl support, and conical trapn'icmbers located within the receptacle and communieating with the tapered entrances and pro-` vided with outlets communicating'vvith the interior ot the said receptacle.

E2. i fly trap comprising a rear support adapted be secured to a fiyscreen'and pro `vided with depending tapered blocks having upwardly converging opposed edges formine` flaring entrances, screen material bridgthe spaces between the blocks, a trap receptacle extending along and mounted upon the rear support, and inclined hollow conical trap members mounted upon the rear support and cwerlappingthe upper ends ot the spaces between the taperedblocls and located within the said trap receptacle and having; outlets communicating with the interior thereof.

5E. fiy trap adapted to be mounted on a lly screen and inclridingq a rear support comprising a horizontal bar and a transverse series ol tapered blocks arranged at the lower edge 'of the said bar and having vopposed upwardly converging side edges, strips of screen material secured' to the blocks and bi dging' the spaces betr/'een the said convergingl edges, end Walls mounted on the rear support'7 one of the end Walls being provided with an openingand having a closure for the same, the connecting Wallof screen material secured to the end Walls and forming;` a trap receptacle, andhollovv conical trap members mounted onthe rear support and arranged at an inclination and located Within the trap receptacle and having lower marginal attaching portions and pro# vided' at their apexes with outlets communicating' with the interior ot the trap receptacle. v

4. The combination Witha fly screen having;` a screen trame and provided at the".` inner edge thereof with a bead', of a fly trap conmrising` a rear ipport having a longitudinal groove to receive the top bead of the fly screen and provided with a transverse series of depending tapered blocks tted between the sidebeads of the fly screen, said support having terminal portions projecting` over the side portions ofthe fly screen, pivoted fastening devices lmounted onrtlie fly screen and movable to engage them with and disengage them from the terminal projectinp` portions ot the said bar, a trap receptacle mounted upon the upper portion ot the rear support1 screen material bridgingr the spaces betnen the tapered blocks, and

hollow conical trap members mounted upon the support at an inclination and communieatin;y at their base portions with the spaces between the blocks and provided at their apexes with outlets; communicating with the interior of the trap receptacle.

ln testimony whereof I have hereunto set my hand.
